Design of relay protection setting calculation module of oilfield power plant based on expert system

摘要

The relay protection setting calculation work of oilfield power plant is so difficult for its heavy work load, long working period and inefficiency. Based on that status, this paper studied the application of knowledge base and inference engine for relay protection setting calculation module of oilfield power plant based on expert system, described the multilevel hierarchic knowledge description method and the inference method based on mixed reasoning. Those methods are applied to the relay protection setting calculation module of oilfield power plant.
